I bought one of those wee folding trowels, surprisingly robust, and it's neither a huge weight or gargantuan sized, very tidy actually, for a quid
I also bought one of their groundsheets, kind of heavy weight if I were carrying it anywhere, but I've left it in beside the spare wheel in the car, a dry clean bit to work on isn't a bad thing
The groundsheet seems sound enough, and at that price, cheaper than the fabric and eyelets to make for myself. I reckon it's a 'useful'.
They also had a pack of long tentpegs. Eight 25cm steel pegs. Heavy but sound enough as spares, and, they work very well as the pot supports through the hobo stove
cheers,
